In scope for the 800G Coherent project is to define interoperable 800G coherent line specifications for campus and DCI applications. The resulting Implementation Agreement (IA) will:

  • Define single-lambda 800G coherent line interfaces for two applications
  • Amplified, single span, DWDM links up to 80-120km
  • Unamplified, fixed wavelength links of 2-10km
  • Support Ethernet client(s) (minimum 100GE) up to 800G aggregate bandwidth

“The next standardized coherent rate beyond 400ZR will be technically challenging with many factors to be considered,” said Tad Hofmeister, Technical Lead, Optical Networking Technologies at Google and OIF Vice President. “With the 800G Coherent IA, OIF is in a unique position to take a leadership role in defining interoperable 800G coherent line interfaces for various applications.”
